TLDR
In this article, a system uses multiple tilt sensors mounted to the vehicle frame and the vehicle suspension system to detect lateral acceleration and lateral load transfer, and a display coupled to the system provides the vehicle operator with a read out of the load transfer ratio and effective center of gravity height.Abstract:
A system uses multiple tilt sensors mounted to the vehicle frame and the vehicle suspension system to detect lateral acceleration and lateral load transfer. The system uses these measurements to determine a lateral load transfer ratio indicative of an actual roll moment compared to a maximum roll moment. The measurements from the tilt sensors are also used to calculate an effective center of gravity height. A display coupled to the system provides the vehicle operator with a read out of the load transfer ratio and effective center of gravity height. The display enables the vehicle operator to more completely understand the nature of the vehicle load and thereby allow the vehicle operator to avoid conditions likely to lead to a vehicle rollover accident.read more

Method for estimating the overturn risk of a vehicle
TL;DR: In this article, a method for redundantly estimating, by means of various sub-methods, the risk of lateral overturn of a vehicle was proposed, i.e. by means, by using the rotational speed behaviour of the wheels on the inside of the turn.

Device for detecting gravity center, device for predicting critical speed for lateral overturn, and device for predicting cargo weight
TL;DR: In this paper, a center-of-gravity detection system was presented, which includes a vehicle capable of carrying cargo and adapted to be towed by a towing vehicle, a shake detector configured to detect shakes in the directions of the self-weight and width of the towed vehicle during travel of the vehicle, and an arithmetic unit (15).
Patent
Vehicle overturn monitor
TL;DR: A vehicle overturn monitor as mentioned in this paper provides a continuous indication of how close the force vector on the vehicle is to the critical angle and a visual/audible warning of imminent danger, as well as an indication of the speed at which the curve may safely be entered, all based on the turning of a knob that moves a critical angle indicator to a point selected by inputting the location of the load into a simple mathematical formula.
